I like the way the linked page uses Web 2.0 when it means scalability.
Great job with the buzzwords.
You know, I was just going to let this go, chalked up as random Internet stranger being an asshat, but seriously. Are you SO bored or jealous of other people's achievements that you have nothing better to do than to sit around and nitpick the friggin' ad copy of a marketing page that was undoubtedly written not just for people who want to know the technical specifications of the product, but common usage applications for it also? What you're calling a "buzzword" is information that business wonks need to know when faced with the question, "Will this solve my problem/fulfill my needs?"
When you develop your own database system, you can write your own ad copy to say whatever you want it to. Or if you prefer, apply for a job at Postgres as their chief marketing guru, and if they're dumb enough to hire you, you can write its ad copy to be purely technical-oriented until the product is completely irrelevant in an actual production environment. ("Now for OS/2 Warp and BeOS!") Otherwise, forgive me if I don't put much weight into your opinion on the matter over the people who have written a kick-ass enterprise-quality system that is pretty much given away for free.
Seriously, what exactly are you implying by your comment, that PostgreSQL isn't a capable database system? That they just use buzzwords instead of actual technical brainpower and muscle as the basis of their software? Because I can tell you that to people who architect, engineer, administer, and eat database systems for breakfast, you are sadly off-base here, and this comment comes off as extremely pompous and ignorant.
